Replacing Bookmarks with Fields in Footer

I am trying to update some of our legacy documents by removing a bookmark and the value it references and replacing the bookmark with the {NUMPAGES} field in the document footer. I have included a document with this issue below.

I have been unable to figure out how to insert a field into a specific place in an already existing Footer. Any help is greatly appreciated.

Footer Bookmark Test File.zip (9.2 KB)

@brandon.hart.idsdoc,

Please try using the following code. Output document is also attached (see 18.12.zip (9.1 KB)):

Document doc = new Document("E:\\Footer Bookmark Test File\\bookmarkTestDoc.rtf");
DocumentBuilder builder = new DocumentBuilder(doc);

builder.MoveToBookmark("TOTPAGES", false, true);
builder.Font.Color = Color.Blue;
builder.InsertField(FieldType.FieldNumPages, true);

Bookmark bm = doc.Range.Bookmarks["TOTPAGES"];
bm.Text = string.Empty;
bm.Remove();

doc.Save("E:\\Footer Bookmark Test File\\18.12.docx");

Thank you for the reply!

I don’t see any changes in the 18.12.docx document. I ran the code you suggested on my file and nothing changed in the footer. However, when I just ran this section of your code:

Bookmark bm = doc.Range.Bookmarks["TOTPAGES"];
bm.Text = string.Empty;
bm.Remove();

The red {NUMPAGES} was removed instead of the TotPages bookmark. This ended up setting the bookmark to !Undefined Bookmark, TOTPAGES instead of removing it completely. I have attached a file showing this named RemoveBookmarkOnly.rtf

I also just ran the InsertField portion of your code:

builder.MoveToBookmark("TOTPAGES", false, true);
builder.Font.Color = Color.Blue;
builder.InsertField(FieldType.FieldNumPages, true);

and it ended up inserting another {NUMPAGES} to the right of the red {NUMPAGES} instead of next to the TotPages bookmark. I attached a file showing this named InsertFieldOnly.rtf

We are working on your query and will get back to you soon.

@brandon.hart.idsdoc,

Please try using the following code to get the expected output:

Document doc = new Document("E:\\Footer Bookmark Test File\\bookmarkTestDoc.rtf");
DocumentBuilder builder = new DocumentBuilder(doc);

string bmName = "TOTPAGES";
doc.Range.Bookmarks[bmName].Text = "";
doc.Range.Bookmarks[bmName].Remove();

doc.FirstSection.Body.RemoveAllChildren();

foreach (Field field in doc.Range.Fields)
{
    if (field.Type == FieldType.FieldFormula)
    {
        FieldFormula formula = (FieldFormula)field;
        if (formula.GetFieldCode().ToLower().Contains(bmName.ToLower()))
        {
            builder.MoveTo(formula.Separator);
            builder.Write(" = ");
            BookmarkStart start = builder.StartBookmark(bmName);
            builder.InsertField(FieldType.FieldNumPages, false);
            BookmarkEnd end = builder.EndBookmark(bmName);
            builder.Write(" - 1 ");

            formula.Start.NextSibling.Remove();
            formula.Update();
        }
    }
}

doc.Save("E:\\Footer Bookmark Test File\\18.12.rtf");
